Abstract (en)

[origin: EP0369069A2] Apparatus for forming a lens pattern for an eyeglass frame includes a guide (14) and a slider (26) mounted on a base (10). The slider (26) can slide longitudinally on the base (10). Also included are mounting pins (28) for detachably holding a pattern (30) on the slider (26). The guide (14) is mounted on the base (10) transversely to the slider (26). A resiliently urged (25) clamping arm (24) is included for holding an eyeglass frame (32) against the guide (14) in a continuously adjustable position. Thus the pattern (30) and eyeglass frame are relatively movable in two dimensions, and alignment of the two during scribing of the frame dimensions on the pattern (30) is facilitated.
